I did not read the detailed description before buying, the same as I don't read the conditions that I supposedly agree to when installing software. Nor does anyone, I expect (apart perhaps from a few lawyers with nothing better to do with their time).
And what is 10 days - or even 24 days - when one is starting out with such a complex program? Most of us also have other calls on our time and even though I viewed as soon as possible as many Serif videos as possible, I didn't discover the lack of support for footnotes until I was importing the text of a book into Affinity Publisher. Even then, I assumed that doing this was just another feature that I had not yet learnt. Starting with a program like this is overwhelming, with hundreds of details to be learnt.
The 50 pages of comments and complaints on this subject on this forum are ample testimony to the disappointment and shock of purchasers when they discovered that such a fundamental feature was missing. Frankly, without it, Affinity Publisher does not merit serious consideration.
